Korenix JetNet 5710G, the revolutionary Gigabit Managed Industrial Power over Ethernet Switch, is designed exclusively for highly critical PoE applications such as real time IP video surveillance with high resolution quality and the evolving demands of wireless communications such as Wimax and 802.11 a/b/g/n Access Points. By software configuration or by LLDP auto detection, the eight 10/100 TX PoE injector ports can deliver 15.4W by IEEE 802.3af or 30W by the latest High Power PoE IEEE 802.3at standard. The total power budget is up to 200W per unit to fulfill local increasing PoE demands. The two Gigabit Ethernet ports provide high speed uplink to connect with higher level backbone switches with Korenix MSR^TM network redundancy technology. Korenix RSR^TM can recover the network failure in less than 5 ms. JetNet 5710G is compliant with EN50155/50121-4/50121-3-2 railway standards and has -40~70°C wide operating temperature range to work reliably under vibrating and shock environments in rolling stock applications.

Driving the IP Surveillance / Wireless PoE market

Since the ratification of the PoE standard in 2003, the Power over Ethernet technology becomes a trend; more devices adopt PD technology to obtain power through Ethernet cable eliminating the need of running separate power wirings to a remote device. In this context, the IEEE 802.3af PoE standard with 15.4 w power budget already satisfies the power needs of most applications, such as 802.11 a/b /g /n wireless AP for Hot-Spots, Air-port Terminations or public internet access as well as a number of IP security applications, which require up to 15.4w power. However, it cannot satisfy the power needs of high end demanding applications, such as WiMAX, IP DOM Cameras, requiring greater than the 15.4w power.

The JetNet 5710G is equipped with the new PSE solution, compliant with both IEEE 802.3af and IEEE 802.3at high power PoE standards. The 8 PoE ports support the LLDP power negotiation function of IEEE 802.3at PoE plus and can deliver 30 watts power per port and 200W per unit to outdoor PTZ IP cameras with direction control for cross–street monitoring, or WiMAX systems for internet access in train stations, airports or Hot-spots. Moreover, the 8 PoE ports of JetNet 5710G integrate forced powering mode function to drive the legacy Powered devices, which does not comfort to the IEEE 802.3 PoE standard. The additional dual Gigabit ports provide more resilient and redundancy for users while forming a ring network and delivering increased bandwidth to the central network.

Power budget limitation with priority control
To power the PoE IEEE 802.3af, PSE device needs to deliver 48V or higher voltage. However, in some environments it becomes hard to obtain enough power budget when the PSE is working with heavy loading. The JetNet 5710G provides budget and priority control to ensure that the total power consumption will not exceed the power limit installed by user. It also provides budget control function to limit the output power in case if the PD device is not claimed right consumption numbers. This feature allows user to protect high priority PD devices from shut down caused by overloading of the power supply.

Comprehensive Redundant Solutions – Multiple Super Ring (MSR^TM)
The JetNet 5710G supports new generation ring technology - MSR^TM (Multiple Super Ring), which includes various new technologies for different network redundancy applications and structures. The JetNet 5710G allows aggregating up to 5 Rapid Super Rings, including 4 Fast Ethernet plus 1 Gigabit Ethernet Rings. With the MSR^TM technology, a node can be configured to multiple rings with the failover time in as little as 5ms and zero-second of restoration time. In addition, users can extend the ring topology by adding hundreds of JetNet series to meet the large-scale network needs without compromising the network speed. The MSR^TM also allows the JetNet series to easily connect with core management switches via standard Rapid Spanning Tree Protocol or through multiple paths or nodes to increase the reliability by RDH^TM (Rapid Dual Homing )(RDH^TM) technology. By integrating MSR^TM and Link Aggregation Control Protocol (LACP) the JetNet series can enhance the link availability and increase the overall link capacity. Two or more Fast Ethernet connections are combined in order to increase the bandwidth and to create a resilient and redundant link.

Rapid Super ring (RSR^TM) Technology

Seamless Ring Port Restoration^TM
Seamless restoration is a new Korenix patented technology which can restore a failed ring without causing any loop problem, topology change and packet loss. With a 0 second restoration time, this mechanism eliminates any unstable status and guarantees the applications running non-stop.

Rapid Dual Homing (RDH^TM) Technology
Rapid Dual Homing is also an important feature of Korenix new generation Ring technology. It supports ring coupling with other vendors devices. Moreover, providing easy configuration and multiple redundancies, the failover time is much faster and the restoration time is zero ms. Uplinks can be auto detected and gathered into groups. In each group uplinks are sorted into primary, secondary and standbys based on their link speed. The uplink with the highest speed is more likely to be active path for data transmission. Link aggregation is also integrated into RDH^TM. An uplink connection can be a single link or several links aggregated as a trunk, which provides better redundancy and link capacity.

TrunkRing^TM

TrunkRing is a new feature in MSR which merges the two technologies of RSR and link aggregation. It takes advantages of aggregation to enhance the link redundancy, while increasing the link speed. The ring will open only if all the aggregated links are broken. Link aggregation can be achieved by either static trunk or LACP. Not all the link sections in a TrunkRing need to be the same. Ring links can be either symmetric or asymmetric. Some are a single path, and the others are aggregated by links where the number of links in a trunk group can be different. Users can enhance the link redundancy at different locations in accordance to the need. The link with less speed is more likely to be used as the backup path for restoring the network to full play capacity.

Link Aggregation Control Protocol

Link Aggregation Control Protocol allows users grouping multiple Ethernet ports in parallel to increase the link bandwidth. The aggregated ports can be viewed as one physical port, so that the bandwidth is higher than just one single Ethernet port. The member ports of the same trunk group can balance the loading and backup with each other. The LACP feature is usually used when higher bandwidth is needed for the backbone network. This is a cost-effective way for transferring much more data.

Auto Topology Discovery & Efficient Management through LLDP and JetView Pro i²NMS
JetNet 5710G supports topology discovery or LLDP (IEEE 802.1AB Link Layer Discovery Protocol) function that can help users to discover multi-vendor’s network devices on the same segment by an NMS system, which support LLDP function. With LLDP function, NMS can easily maintain the topology map, display port ID, port description, system description, VLAN ID, etc..

Once a link failure happens, the topology changed events are updated to the NMS to help users easily maintain the network system. Besides the SNMP and LLDP protocols, JetNet 5710G series efficiently works with the Korenix patented JetView Pro i2NMS, which in addition to the auto-topology discovery, also delivers MSRTM group management, group IP assignment, firmware upgrade, configuration file backup/ restore ,SNMP MIB Browser /compile, etc. Furthermore, users can export the topology map to diverse formats, such as JPG, BMP, PNG and PDF, for easily managing and trouble-shooting the network. The user-friendly software allows administrators to discover devices automatically and efficiently manage the performance of the industrial network.

Outstanding Management and Enhanced Security
The JetNet 5710G provides various network control and security features to ensure the reliable and secure network connection. To optimize the industrial network environment, JetNet 5710G series supports advanced network features, such as Tag and Port-based VLAN, IGMP Snooping, Quality of Service (QoS), Link Aggregation Control Protocol (LACP), Rate Control, etc. The PoE switch can be smartly configured through JetView, JetView Pro (Korenix’s advanced management utility), Web Browser, SNMP, Telnet and RS-232 local console with its command like interface. The failure notifications are sent through e-mail, SNMP trap, Local/Remote system log, Fault event alarm relay. Furthermore, the built-in watchdog timer of JetNet 5710G allows users to recover system when CPU failure is detected.

To avoid hacker’s attacks and ensure the secure data transmission, JetNet 5710G series features DHCP client, DHCP server with IP and MAC binding, 802.1X Access Control, SSH for Telnet security, IP Access table, port security and many other security features.
